United States PatentO INSECTICIDE BOMB Fred W. Kenline, Lancaster, N. Y.

Application April 16, B54, Serial No. 423,759 3 cla ms. (Ci. 43-7132 This invention relates toimprovements in methods and means for spraying foliage with disease preventatives and insecticide powders and/or'solutions.

Whereas, various hand-spray and truck-based power spray and aerial spray arrangements have been previously developed for the purpose of spraying crops, shrubs, trees, and the like with powders and solutions, such devices of the prior art have proven to be objectionable either from the standpoint of difficulties attendant their use or cost of operation. The present invention countemplates, broadly, provision of a novel type bomb such as may, with utmost facility, be projected or otherwise disposed in the center of a foliage mass to be treated; said bomb comprising a frangible container with an explosive device therein, and including means integral therewith facilitating manual placement of the bomb at ideal operative position without special tools or equipment.

More specifically, the invention contemplates provision of a bomb which comprises generally a container in the form of a readily frangible bag or shell having a filling opening and a closure device therefor which also functions as a mounting means for a suspension or the like and for the explosive charge detonator components of the device. Furthermore, the invention contemplates use of a container as aforesaid which is so shaped and constructed as to break open upon ignition of the explosive charge therein so as to disperse the contents in all directions, thereby providing an improved dusting of the foliage under treatment.

Whereas, the invention may be embodied in a variety of physical forms and arrangements; it is illustrated by way of example herein by the accompanying drawings wherein:

The drawing shows a sectional view through the insecticidebomb of the invention.

In the drawing the device of the invention is illustrated to comprise a generally cylindrically shaped container comprising a circular wall portion 70 formed of frangible paper or plastic or metal foil or other suitable material, and closed at its opposite ends by means of circular plugs 72, 74 which may be formed of wood or plastic or rubber or any other suitable material. The upper plug 72 carries a suspension hook 75, and the lower closure member 74 mounts a detonator cap 76 in such manner that the body portion thereof is disposed within the insecticide dust charge 78. A spring trigger device for the cap 76 is illustrated at 79 as being arranged to be actuated by means of a pull cord 80 looped over the free end of the trigger spring 79. Thus, when the device is suspended in a tree or the like by means of the suspension hook 75, the cord 80 may be pulled upon downwardly until it deflects the spring 79 away from the cap and until such time as the string 80 slips off the end of the spring 79, whereupon the latter springs back into detonating contact with the percussion cap portion of the device 76. The cap thereupon explodes to scatice Patented Oct. 21, 1958 the novel insecticide bomb device thereof may be used a with utmost facility and convenience and without special tools or equipment while obtaining optimum dispersion of the insecticide dust charge throughout any preselected mass of foliage in greatly improved manner, compared to prior methods and means developed for similar purposes. For example, groups of bombs of the invention may be readily packaged in compactly nested relation in card board cartons or the like, and distributed through retail stores such as are customarily frequented by home owners, gardeners, and amateur or-professional orchardists and nurserymen and the like. The bombs may be simply removed from theshippingcarton and tossed in the manner of a base ball or hand grenade or otherwise disposed in the center of the mass of foliage to be treated, whereupon the detonator device will operate so as to cause the bomb to explode thereby dispersing the insecticide powder throughout the foliage mass with optimum results.

The bomb may be hooked upon the upper end of a pole by means of a hook device as illustrated in the drawing, or otherwise tied to the upper end of a pole which is then thrust up into the center of the tree foliage. Subsequent explosion of the bomb by operation of a percussion cap as shown in the drawing will scatter the insecticide dust as explained hereinabove.

Or, in the case of unusually tall trees, a wire or string or the like may be fixed at one end to any suitable weighted object, and the latter may then be thrown over an upper branch of the tree. Then, the bomb may be tied to one end of the string and the other end of the string then pulled upon so as to draw the bomb up into the tree at the desired position therein prior to explosion of the bomb as explained hereinabove. In all such cases, the bomb as shown in the drawing may be employed. If such operations are conducted just subsequent tosprinkling or rain-fall, the foliage will thus be Wetted and the insecticide dust will of course adhere thereto in improved manner for maximum results.

It will of course be understood that the bomb as shown in the drawings herewith is adapted to be used for spraying low growing foliage such as garden produce, shrubs, and the like; the bomb in such case being simply laid on the ground under or closely adjacent the foliage to be sprayed, whereupon explosion of the bomb will disperse the contents thereof in all directions so as to scatter the insecticide dust contents for optimum results.

Thus, the bomb device of the invention is of improved versatility; inexpensively manufactured, and easily packaged in cartons or the like for utmost convenience in distribution and retail sales purposes. The purchaser, without need for special tools or equipment, may employ the bomb device wherever indicated with utmost ease and facility.

It will of course be appreciated that whereas the bomb illustrated and described in detail is referred to as an insecticide bomb containing powder or dust, other material desired to be sprayed may be used therein with equal facility, and that although only one form of the invention has been shown and described in detail, it will be apparent to those skilled in the art that the invention is not so limited but that various changes may be made therein without departing from the spirit of the invention or the scope of the appended claims.
